GROOVED BEARINGS LUBRICATED BLOOD

1.血液润滑的基本方程用卡森公式推导出流体膜润滑的基本雷诺方程，用它来近似血液的非牛顿粘度。结果表明：1.流体流量与压力梯度之间的关系在表达式和图形上都有表达，但没有推导出关于血液润滑的狭缝理论。基本形状沟槽轴承的检验本人提出的用于血液润滑的沟槽轴承，其结构是轴承外部的血液不流入轴承内部，轴承内部受伤的血液不会泄漏到轴承之外。对血液润滑沟槽轴承的特性进行了检测，确定了基本形状和轴承参数。在有限槽数的情况下，通过精确的数值分析，考察了轴承端部的局部血液流量。结果表明，窄槽理论与有限槽数的精确分析结果基本一致。实验装置的设计实例对血液润滑的槽形轴承进行的数值分析假定为牛顿粘性，因为血球在轴承内部被破坏。为了证实这一现象是否真的存在，本研究计划在本研究结束后对血液润滑的沟槽轴承进行实验。该实验装置的设计是在本研究中进行的。

1. Fundamental equation of the blood lubricationThe fundamental Reynolds equation of the fluid film lubrication is derived by Casson's formula by which the non-newtonian viscosity of the blood is approximated. The relation of the mass fluxes and the pressure gradient was shown in the expression and figure, but the Narrow Groove Theory on the blood lubrication was not derived.2. Examination of the grooved bearing of basic shapeThe grooved bearing which was proposed by me for the blood lubrication, has the structure that the blood outside the bearing does not flow in internally in the bearing and the hurt blood inside of the baering is not leaked besides the bearing. I examined the characteristics of the grooved bearing lubricated by blood and decided the basic shape and bearing parameters. The local blood flux at the end of bearing was examined by the precise numerical analysis on the case of finite grooves number. It was clarified that the Narrow Groove Theory gives the almost same results to the precise finite grooves number analysis.3. Example of designing experiment deviceAbove numerical analysis on the grooved bearings lubricated by the blood assumes the newtonian viscocity, because blood corpuscles are destroysed inside the bearing. To confirm whether this phenomenon happens actually, the experiment on the grooved bearing lubricated by blood is planned after this resaerch ends. The design of this experimental device was performed in the present research.
